Deck — Deck Power Evaluation
Final Contextual Deck Power: 20/100 (±8 · Confidence: Low)
| Overall score | Value |
|---|---|
| Structural Deck Power | 49 |
| Going First | 48 |
| Going Second | 55 |
| Meta Power | provisional |
| Tournament Reliability | 45 |
- Primary strategy: Toolbox
- Secondary strategies: Stun, Midrange
- Format: ocg
Legality
Main 55 / Extra 15 / Side 0 — status: Illegal. 4 violation(s).
Identity & game plan
- Win condition: Link and Xyz pressure from the Extra Deck (Accesscode Talker, Decode Talker Heatsoul, Transcode Talker, Primathmech Alembertian) once the Mathmech/Cyberse starters are live; Hand-trap and negation control that trades cards 1-for-1 until a Link board is established
- Turn 1 (going first): Open a Cyberse starter (Pikari @Ignister, Effect Veiler or Mathmech Diameter) and convert it with Mulcharmy draw-or-search pieces toward a Link-3 or Link-4 monster
- Turn 2 (going second): Hold 17 hand-trap/negation cards (about 90% to hold at least one in a 6-card hand) and answer the opponent's first Summon before rebuilding
- Recovery: Mulcharmy Fuwalos and Mulcharmy Purulia draw cards when the field is empty, and Ash Blossom, Effect Veiler and Droll recycle from the hand to answer the next interaction
- After siding: No side deck is present, so no post-side plan can be evaluated
Why it scores here
The deck is a mixed Mathmech, Cyberse and Ignister toolbox: exact-name Mathmech purity is only 11.4% (8 of 70 archetype-tagged copies), with 62 off-archetype copies spread across Ignister, Code Talker, Mulcharmy, Solemn and Salamangreat. The engine is reachable (P(at least one of the 15 archetype-core copies in a 5-card hand) ≈ 0.81), but no recorded boards exist, so the combo ceiling and median are text-only inferences and score low. The strongest signal is interaction: 17 hand-trap and negation cards give about a 90% chance of at least one answer in a 6-card going-second hand, which earns the going-second and interruption-resilience scores. Popularity and archetype share earned nothing, and the card scores were not averaged. The Structural score (about 49) is capped to 20 because the list is illegal (two Forbidden cards and two copy-limit violations), so this is a structural-only read.
Dimension scores
| # | Dimension | Score | Evidence |
|---|---|---|---|
| D1 | Engine Accessibility & Consistency | 55 | P(≥1 of 15 archetype-core copies in 5-card hand) ≈ 0.81; engine diluted by 62 off-archetype copies (Inferred) |
| D2 | Opening-Hand Quality & Brick Management | 45 | 22 level-0 cards and 17 hand traps compete for hand slots; proxy full-brick ≈ 0.19 (Inferred) |
| D3 | Combo Conversion & Ceiling | 40 | No parseable recorded boards; ceiling relies on Link/Xyz enablers in the Extra Deck (Inferred) |
| D4 | Combo Floor & Median Output | 35 | No combo samples, so median output is unmeasured and set low (Inferred) |
| D5 | Interruption Resilience & Route Redundancy | 60 | 17 hand-trap/negation cards and multiple Link recursion routes give several answers after one disruption (Inferred) |
| D6 | Resource Economy, Recovery & Grind | 55 | 11 searcher-text cards and Mulcharmy draw effects provide recovery; no resource telemetry (Inferred) |
| D7 | End-Board & Interaction Quality | 65 | 19 negation-text cards and 15 removal-text cards provide breadth of end-board interaction (Inferred semantic) |
| D8 | Going-Second & Board-Breaking Power | 65 | P(≥1 hand trap in 6-card going-second hand) ≈ 0.90; negation density is high (Inferred) |
| D9 | Offensive Pressure & Closing Power | 50 | Link-4/5 and 3000-ATK Extra Deck threats exist, but no closing sample exists (Inferred) |
| D10 | Main Deck Efficiency & Flexibility | 40 | 55 Main cards across 32 distinct names; 22 level-0 cards and 62 off-archetype copies lower compactness (Inferred) |
| D11 | Extra Deck Efficiency & Coverage | 55 | 15 Extra Deck slots carry 10 Link monsters across several sub-archetypes with no shared route (Inferred) |
| D12 | Side Deck Adaptability | 10 | No side deck exists, so post-side adaptability cannot be assessed; set to floor (Verified) |
| D13 | Matchup Coverage & Format Fit | 40 | No tournament link or dated meta sample; format fit is Provisional |
| D14 | Pilotability & Error Tolerance | 30 | Multi-archetype engine with many conditional hand-trap timings is hard to pilot consistently (Inferred) |
How the score was computed
Strategy profile: Toolbox primary; Stun secondary used for interpretation only, not blended into weights. Structural ≈ 49, Going First ≈ 48, Going Second ≈ 55, Meta = provisional, Tournament Reliability ≈ 45. Modifiers: banlist_exposure (-8); no_side_deck (-3). Final formula: Illegal list: uncapped 0.80*Structural(49) + 0.20*TournamentReliability(45) + modifiers(-11) ≈ 38; capped to 20 as a structural-only result per the legality rule. Meta Power provisional/null.
Probability & combo summary
- Opening a starter: P(≥1) ≈ 0.81 · key two-card combo ≈ — · full-brick estimate ≈ 0.19 (all Inferred)
- Combo output: best PowerIndex —, median —, board-per-starter —
- Turn order: 0 going-first lines vs 0 going-second lines
Strengths
- Dense hand-trap and negation package (17 hand traps, 19 negation-text cards)
- High chance of at least one answer in a going-second 6-card hand (≈0.90)
- Multiple recursion and draw routes (Mulcharmy, Droll, Effect Veiler)
- Strong Extra Deck link coverage (10 Link monsters)
Weaknesses
- Illegal list: two Forbidden cards and two copy-limit violations
- Low exact-archetype purity (11.4%), with engine pieces spread across several sub-archetypes
- 22 level-0 cards and 32 distinct names reduce compactness
- No side deck
- No recorded boards to confirm combo conversion
Critical choke points
- Mathmech Circular and Mathmech Sigma as the only exact-archetype Link/Synchro enablers
- Single copies of most Extra Deck links, so losing one removes a route
Recommended changes
| Priority | Remove | Add | Reason |
|---|---|---|---|
| 1 | Called by the Grave; Triple Tactics Talent | Legal substitutes (none chosen here) | Both are Forbidden in OCG, so the list cannot be played as built |
| 2 | One Ash Blossom & Joyous Spring (3 → 2 copies) | Any legal card | Semi-Limited limit is 2 |
| 3 | One Droll & Lock Bird (2 → 1 copy) | Any legal card | Limited limit is 1 |
| 4 | Off-archetype 1-ofs | Exact-name Mathmech or Ignister support | Raises archetype purity and engine consistency |
Evidence & confidence
- Verified: Legality status Illegal with four copy/ban violations; Banlist status of each restricted card; Main/Extra counts (55/15) within OCG size rules
- Inferred: Core-engine access ≈ 0.81 in a 5-card hand; Full-brick proxy ≈ 0.19; Going-second hand-trap coverage ≈ 0.90; Interaction density from negation and removal text
- Provisional: Meta Power (no dated metagame sample); Format fit and matchup (no tournament link)
- Data gaps: no combos supplied — combo floor/median/ceiling is text-only inference no tournament link — archetype meta-share and per-pilot match record absent no win-rate telemetry exists in YGOVN — going-first/second, matchup, brick/starter/OTK rates are Inferred or Unknown Meta Power is Provisional unless a dated metagame sample is supplied no side deck present
